From Reuters:
Shifting China’s model of urbanization to favor huge supercities could boost per capita output, improve energy efficiency and help contain the loss of arable land, the McKinsey Global Institute (MGI) said on Monday.
Rapid urbanization has been a major driver of Chinese growth over the past two decades and will become more so over the next 20 years; cities will account for 95 percent of China’s gross domestic product by 2025, up from 75 percent today, MGI said.
But the institute, the economics research arm of consultants McKinsey & Co, said in a report that China could reap even greater economic benefits by adopting a more concentrated pattern of urban growth.
